Engine light comes on even after all sensors where replaced on 1999 ford windstar?
Just replacing a sensor that was the source of a 'trouble-code' doesn't mean the true *cause* of the problem was fixed.
It's really important to research those trouble codes *BEFORE* replacing sensors.
It's time to go back and have those codes read again and then learn about what causes them.
